Rihanna vs. Beyonce 'beef' over? Jay-Z cheating rumors FALSE after Solange Knowles attack, wife shares 'BFF' Met Gala Instagram PHOTO with Drake's girlfriend

Following the 2014 MET Ball Gala, Solange Knowles attacked Jay-Z in an NYC hotel elevator. Rumors initially suggested that the songstress was "protecting" her older sis, Beyonce (because HOV was getting a little too "flirtatious" with fellow pop princess, Rihanna). Check it out:

But apparently, Queen Bey wants fans to know that things are "totally cool" between her and Drake's on-and-off again girlfriend. The two Hollywood beauties actually hung-out at the MET Ball Gala earlier this month - and the "Drunk in Love" superstar recently reposted this Instagram snapshot to prove it:

The annual, celeb-studded fashion event was held on May 5 - so why would Bey post this "BFF" image now? Maybe she's trying to send a message... that she doesn't believe all of the "RiRi and Jay-Z secret affair" hype!

Things seem to be going well between the hip-hop power couple. The duo released this statement just last week, regarding Solanges' epic elevator fight:

“As a result of the public release of the elevator security footage from Monday, May 5th, there has been a great deal of speculation about what triggered the unfortunate incident. But the most important thing is that our family has worked through it. Jay and Solange each assume their share of responsibility for what has occurred. They both acknowledge their role in this private matter that has played out in the public. They both have apologized to each other and we have moved forward as a united family. The reports of Solange being intoxicated or displaying erratic behavior throughout that evening are simply false,” adds the release. “At the end of the day families have problems and we’re no different. We love each other and above all we are family. We’ve put this behind us and hope everyone else will do the same.”

So, do Mstars fans think Bey's ongoing "beef" with Rihanna has finally fizzled out?
